Ten minutes from Ploerdut is the town of Guéméné sur Scorff, historic home of the Princes of Rohan . There are several restaurants (try The Three Merchants for another lunchtime feast with Celtic décor and music), shops, cafes and an excellent supermarket with cheaper petrol.
Close at hand is Priziac, with a large swimming lake. It is ideal for families, with beach, boats and a cafe. Further afield, the south coast around L'Orient, including the beaches of Larmor Plage, is about 40 minutes' easy driving on quiet roads. Pre -historic Carnac , the city of Vannes , the Quiberon Peninsula and the Gulf of Morbihan for wildlife and water sports are reached in about an hour. To the north is a very secenic drive around Lac de Guerladen with swimming, sailing and lakeside restaurants.
A further 20 minutes drive brings you to the medieval/Napoleonic city of Pontivy with all amenities. This is the area's major centre and well worth a visit.
On average, the sun shines for about 2200 hours every year and long, warm summers are pretty much guaranteed . It can be cold in winter, but even in January, a fine day is never far away. Spring and autumn are magical times to visit.
There's plenty to do apart from lazing about, including cycling and walking (try the Nantes-Brest Canal trail), riding, golf and any amount of beach based activities.
